Frisco man known for scrambling local mountains dies on slick ridgeline

May 21 — Friends and family are mourning for Michael Sanchez, aka Boris, a 49-year-old Frisco man who died scrambling a rocky ridgeline just west of Main Street Frisco on May 19.

Authorities believe Sanchez was running solo when he slipped and fell on Wichita Mountain. The 10,855-foot peak was slick and icy with patchy snow. Summit County Rescue Team recovered his body May 20.

“We called him Boris,” a friend, who asked to remain anonymous, told Krystal 93. “We’d look up on Buffalo Mountain (near Silverthorne) and see his tracks and say, ‘There’s Boris.'”

Sanchez regularly ran the Wichita route in shorts and running shoes. Official cause of death is pending autopsy.

He leaves behind a 17-year-old daughter.

FRISCO, Colo. — A solo hiker slipped and fell to his death yesterday scrambling a slick, rocky ridgeline at the far west end of Frisco Main Street.

Summit County sheriff reports the unidentified man was on Wichita Mountain, one of two small peaks near the entrance of North Tenmile Creek Trailhead at Exit 201.

The ridgeline, known locally as Falcon Ridge, is steep and rocky with sheer cliffs on both sides. New snow and cold temperatures yesterday made the route slick.

Around 6:30 p.m. yesterday rescuers entered the field via North Tenmile to search for the missing hiker. Rescuers told Krystal 93 the man’s friends were already looking for him.

Today Summit County Rescue Group is sending rope teams to recover the body with help from a helicopter. The operation could take several hours. Please avoid the area.

The victim’s name is pending recovery by rescuers and identification by Summit County coroner.
